INCINERATOR.

Specification of Letters Patent.

Application filed July 15, 1911. Serial No. 638,723.

To all whom it may concern:

Be it known that 1, WILLIAM C. MCKE- owN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Incinerators, of which the following is a specification.

My invention relates to improvements in incinerators for the disposal of garbage, excrement, and other matter, and it has for its primary object the provision of an incinerator formed of units or sections so that it may be constructed in difierent sizes by assembling difierent numbers of units or sections, and so that when constructed it may be enlarged or diminished in length, as may be found desirable or necessary.

Another object of my invention is the production of a simple, inexpensive, and effective incinerator in which comparatively few parts are employed and in which both solid and fluid orliquid matter may be quickly reduced and consumed.

WVith these and other objects in view to appear hereinafter, my invention consists in the construction, arrangement and combination of parts tobe hereinafter described and particularly pointed out in the subjoined claims.

In the drawings, Figure 1 is a side elevation of an incinerator embodying my invention in a representative form. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation. Fig. 4 is a central longitudinal section, on a slightly enlarged scale. Fig. 5 is a horizontal section on a slightly enlarged scale, taken on line w w, Fig. 1. Fig. 6 is a transverse section taken on line 00-00, Fig. 1. Fig. 7 is a transverse section on a slightly enlarged scale, taken on line y-y, Fig. 1. Fig. 8 is a plan view of one of the closure plates and its cooperating kettle. 9 is a transverse section taken on llnev Fig.

Fig. 8. Fig. 10 is a plan view of one of the closure plates.

Referring now to the drawings in detail, corresponding numerals of reference refer to corresponding parts in the several figures.

The reference numeral 8 designates the casing consisting of a plurality of sections 9 connected together in an operative manner so that they may be disassembled and one or more sections dispensed with, or additional sections added thereto, as may be found desirable or necessary. Each section forms a unit adapted for use with another or any other number of units, to form a complete incinerator.

The casing may be constructed of castiron, sheet metal, or any other suitable material, but by preference and as herein shown and described, it is made of cast iron; each unlt or section comprising two spaced side members 10 and a top plate 11 and each side membercomprising two parts 12, 13, one surmounting the other. The lower part of each side member serves as a leg or support while the upper part is made hollow and with the other corresponding upper parts serves as an air channel, designated by the numeral 14. The side members are therefore arranged in two spaced sets, the members of each set being in alinement. Each lower part or leg is connected with the adjoining leg or legs, by means of bolts 15 and the upper or channel parts of each set are connected together by a bolt 16 extending from one end of the casing to the other. The space 80 between the two sets of side members is closed at the top by the topplates 11, each of which is preferably inclined laterally in opposite directions from its medial point and in each inclined portion is an opening 17 over or around which is fitted a closet seat 18. Fitted onto each closet seat is a cover 19 to close the opening in the closet seat and the opening in the top plate directly beneath. The covers 19 may be hinged or otherwise secured so that the openings in the seats 18 are exposed, and the seat may also'be hinged or otherwise applied so that they may be raised or removed from the top plates, as may be desired.

' The front of the casing is closed with a plate 20 conforming in shape to the crosssectional shape of the units or sections and closing the front ends 'of the channels 14: and the space 80 between the side members 10. This plate is secured in place by means of the bolts 16 and also by means of bolts 81 passed through the forward lower parts or legs 13. The rear of the casing is also closed with a plate 21 of similar shape serving to close the rear end of said space, but having openings 22 which register with the channels 14, for a purpose to hereinafter appear. This plate is also held in position by means of the bolts 16 and bolts 82 that are passed through the rear lower parts 1 or legs 13.

The lower parts or legs of each side member have ledges 23 projecting inward from their inner surfaces on which are supported the grate sections 24, the liquid capacity tank 25, and the liquid evaporating tanks 26.

In the embodiment of my invention herein disclosed, four units or sections are shown, and the grate and liquid evaporating tanks which lie at opposite sides of the grate extend from the front end of the casing to the rear end of the second unit or section, while the liquid capacity tank extends from the front end of the third unit or section to the rear end of the casing. The liquid evaporating tanks are removable from the casing'through openings 27 in the front plate and are fiangechasat 28, to limit the extent to which they are inserted into the casing. By means of boltsor screws passed through the flanges 28 and taking into the front plate 20 said evaporatingtanks are held securely in-place and as they are positioned vat opposite sides'of the grate they form the sides of the fire box 29. The liquid capacity tank spans the space ,80 and receives support at its longitudinal marginal portions from the ledges 23. It is positioned directly in rear of the grate and the liquid evaporating tanks and serves as a bridge wall for the furnace portion of the incinerator. V

. Arranged in a plane between the top of the casing and the liquid capacity tank and grate, are rectangular closure plates 30, one plate being provided for each unit or section. Each plate has an opening 31 in which, under normal conditions, fits the upper end of a kettle 32, in which is to be deposited garbage, excrement, or other matter to be disposed of. With the kettles 32- in the front plate, which opening may be closed .by a door 36. Said fuel openingextends beneath the plane inwhichv the grate is held so thatoaccess can be had therethrough to the ash pit" 37 beneath the grate.

- Underneath theliquid capacity tank 25 is a space 38 which is practically acontinuation of the ash-pit and serves as an air passage *in communication with vertical airfiues 39 secured to the back plate of the casing through openings 40 in said plate. The upper ends of said air fines are in communication withthe space 33 above thekettles through openings 41 in said back-plate and said space 33 is in communication at its front end with the channels it in the side members of the casing through openings 42.

Secured to the back plate of ;the casing is a smoke-box 43 having a smoke pipe 14: attached thereto and by means of openings 45, 46 in said back-plate, said smoke box is easily manipulating the damper while attending to the fire. V a V V At'the rear end of the incinerator 'a urine or liquid receiving tank 419 is located which partly surrounds the smoke box and has two flues50 extending upward therefrom which are in communication with the passages lat in-the side members through the openings 22 in the back plate. Said liquid receiving tank has a number of openings 51 in its top wall, closed or adapted to be closed by lids 52 hinged to said wall so that the openings may be closed when the tank is not in use. Said tank has also an opening 53 in its rear wall for admission of air into the tank at all times. The bottom of the tank preferably slopes to a common point, atwhich a dischar e pipe 54 is secured which leads the liquid into the liquid capacity tank, as at 55, and in order to prevent clogging of said pipe, a screen 56 is placed in the liquid receiving tank a distance above its bottom. A screen 57 is also fitted to the opening 53 to prevent the mischievous insertion into the tank 49 of solid or other matter likely to clog the discharge pipe 54L.

Each of the closure plates 30 comprises a plate portion 58 having the opening 31 therein conforming or approximately conforming to the contour ofthe kettle to provide a space 84: between the two, the space atone side of the kettle being somewhat larger than at the other side thereof so as to form shoulders 85 at opposite points. Each closure plate haspa, marginal flange 59 through which bolts, screws, or other fastening means are passed that take into or pass through the inner walls of the side members to securely fasten the plates in place. Ad-

joining closure plates abut against each- 7 other and the front and rear plates 21, 22,

respectively,of the casing. The kettles are so arranged in the closure plates'thatlthey may be turned or rocked therein to, dump the contents and so that when in normal po sition, they efiectually close all communication between the spaces 33, 34:; For this I purpose each kettle has two flanges -60, 61

arranged indifferent horizontal planes so that when one lies against the underside of its cooperating closure plate 30, the other liesagainst the upper side thereof, asbest shown iii-Figs. 4, 7 and 9. The flange of each kettle bearing against the upper side of the closure plate is somewhat narrower than the flange bearing against the under side thereof and serves to close the narrow portion of the space 84 between the kettle and the closure plate while the flange bearing against-the under side of said closure plate serves to close the wider portion of the space between the kettle and said plate, as best shown in Fig. 8.

Each kettle has a pair of hollow trunnions or pivots 62 arranged preferably in a plane beneath the flanges 60, 61, each of said trunnions being journaled or supported in a U-shaped bearing 63 which opens into a vertical liquid duct 64 cast within the upper part of the cooperating side member and having a lateral extension 65 at its upper end opening through the outer wall of said side member and arranged in line with the hollow trunnion or pivot so that access may be had to the same and to said vertical liquid duct for cleaning them in the event of their becoming clogged and alsoto permit the insertion of a suitable tool into the hollow trunnion, which is made square in-.

may overflow into the vertical liquid ductswhen the level is above the lowest points of the bores of the trunnions or pivots, and

from there be delivered into the capacitytank by the pipes 66 at opposite sides of the incinerator. The lateral extensions 65 of the liquid ducts are closed by screw-plugs 68 or otherwise so that there can be no escape of liquid matter therethrough. One of the flanges of the kettle extends from one side thereof and terminates at points beyond the plane in which the pivots of the kettle are arranged while the other flange extends from theother side of the kettle and terminates at points in line with or substantially in line with the extremities of the first mentioned flange, said flanges terminating also in line with the shoulders in the openings 31. The extremities of the flanges are beveled, as at 75, so that the closurevplate may be swung on the kettle and drawn to one side for removing the same, the enlarged portion of the opening 31 permitting the narrow flange 60 to pass therethrough.

- The liquid capacity tank is connected with both liquid evaporating tanks by means of pipes 69,v in each of which is a union 70 to permit of conveniently disconnecting the evaporating tanks and the capacity tank. Each of the liquid evaporatingtanks and the capacity tank have overflow pipes 71;

fastened'into' the bottoms of the tanks and extending up within short distances of their tops. The overflow pipes in the evaporating tanks are particularly desirable owing to the tendency of urine to foam andboil over when heated.

The use and operation of the apparatus is as follows :The kettles 32 are used to receive solid matter, such as excrement and During the accumulation of the solid.

matter, the damper 47 in or for the opening 45 in the back-plate is open so that the foul odors from the accumulated matter may escape through the smoke stack, which rises to a sufficient height to create the necessary draft and direct the odors to a region beyond detection.

When the contents of the kettle contain liquid matter, such matter may overflow through the hollow trunnions or pivots 62 and pass into the liquid capacity tank and from said capacity tank into the liquid evaporating tanks, and as the connection of the capacity tank to each evaporating tank is near their bottoms, the liquid in both is maintained on a level. When the kettles contain suflicient matter, a fire is built in the.

fire box, and at such times the damper 47 is closed so that the odors and gases from the solid matter and also those from the liquid matter escaping through the overflow pipes 71 in the evaporating tanks, are drawn through the fire andthereby consumed.

'The outer air is drawn into the liquid receiving tank 49 through the opening 53, thence through the flues 50 to the passages 14, from the latter through the openings 42 in the side members of the foremost or first section to the space 33 above the kettles where it mingles with the gases and odors From the space 33 the gases and odors are drawn into the air flues 39, thence through the openings 40 to the space 38 and ash-pit 37, and finally through the grate and fire to be consumed. The products of combustion pass through the space 34 underneath and around the kettles 32, then through the opening'46 into and out the smoke pipe. During such action incineration of the matter in the kettles takes place and the liquid matter in the evaporating tanks is also consumed, and at such times the closet seats 18 and covers 19 are elevated or removed and metal plates fitted over the openings 17.

When the solid matter in the kettles is incinerated,the kettles are turned or rocked on their pivots to dump the ash therein onto the fire and the liquid capacity tank, from of the accumulated solid matter.

which latter it may be drawn forward'onto the fire.

When decreasing the number of. units or sections, a smaller fireplace or a smaller capacity tank may be used, 'or both a smaller fire place and capacity tank, and when increaslng the-number of units or sections a larger fire place or a larger capacity. tank may be used, or both a larger fire place and capacity tank, as may be found desirable or necessary.

It is apparent'that minor changes in construction and arrangement of parts may be resorted to without departing from my in= vention or sacrificing any of the advantages thereof:
